A group of people sacrifice their lives or well-being to save one child
spoilers for the three shows: Jojo part 6, To Be Hero X, and Attack on Titan
Attack on Titan - >!During the rumbling, a group of people are being shoved off a cliff as the giant titans step closer and closer. People are desperate to run away from the titans, but in doing so they push others off the cliff. A woman, who desperately wants her baby to be saved, reaches forward so it might have the extremely small chance to survive in case the titans stop or are killed. One by one, the people being shoved off the cliff hand the baby to the person in front of them, as they themselves perish, in the hope that this one child can survive!<
Jojos: Stone ocean ->!While fighting Pucci, they get outsmarted by him, when Anasui was going to sacrifice himself to allow Jotaro to stop time, during stopped time Jotaro realizes Pucci targeted his daughter, and instead of finishing off Pucci, attempts to save his daughter, and pretty much dies in the process. Jolyne, who realizes they have zero way to beat pucci now, attaches Emporio to a dolphin with her string, using all of it in her body to ensure his safety as the dolphin swims faster than Pucci can, and allows him to escape the reset of the universe, and finish off pucci later. This might not fit for the post, but I really like it anyways.!<
To Be Hero X - In a world about being popular giving you super powers, this bullshit move actually makes a LOT of sense. >!In a plane about to crash, everyone on the plane gives their wishes and luck to a single baby, Lucky Cyan, so she can survive the crash as the sole survivor.!<
